Probably is more sluggish off the line with an unlearnd PCM. One your PCM
gets up to date almost all the low end will come back. Try taking it to the
high end (5000+RPMs) you should feel a gain immediatly after install.

Yes agree on PCM, The butt dyno will feel more HP and you milage would go up

PCM learning will take care of most the ideling and squeaking. But it still
freaks every once in a while. I think the squeaking is air going the idle
control bypass hole thing.
